As far as my designs are concerned when I compare them with other churro shop logo over the Internet I find my ones do not suit the " shop" feeling.
When works get rejected there are absolute reasons. If someone pre-mention the reference choice it would nicer.

One may copy from stock images but then one should not say words such as "without plagiarism".

Also, there are many who does not know how many files one had to deliver both Vector as well as Raster in a Final File format logo design, still they do stunning designs even better than an in-house designer. It depends on the designer's own creativity and experience of work and more work. Design creation and acceptance of that design are more a subjective & contextual matter.

One should know that on the other end there are people who may be well experienced and professional too.

Hi, my work is 100% done by me personally # 11, without plagiarism, it's all done in a vector and can be enlarged to large sizes without losing quality (including churro). Also, Godzilla would be a good talisman for your company, and I can easily changr the font if you don't like it. Please note that not all the entries can be used in advertising,because many are pixel images from non-professional freelancers. I'm waiting for a feedback from you and I wish you a nice day!
